APPARATUS FOR USE IN VENTILATING WITH CONDITIONED R FILTERED, COOLIiD, 0R WARMED AND MOISTE NED AIRI Specification of Letters Patent.

- J Application filed August 9, 1904. Serial No. 220,186.

Patented Oct. 16, 1906.

To all whom it may concern:

Be it known that I, JOHN ALSTON HART, engineer, a subject of the King of Great Britain and Ireland, residing at Commercial.

Mills, N o vas, Blackburn,'in the county of Lancaster, England, have invented new and useful Improvements in Apparatus for Use in Ventilating with Conditioned or Filtered,

through moistened permea le material such, for example, -as coir or cocoa-nut mattingbefore it is distributed in the room or place to be ventilated. Apparatus of this character is described in the specification of Letters Patent No. 691,312, of 1902, granted to me.

The object of my present invention is to i prov de an apparatus which is more efficient,

cheaper in first cost, and more convenient in z use and also easier to clean; and this is chiefly effected by the arrangement of the permeable material and the means for moistening it, as hereinafter described, so that 1n a given space a greatly-extended area of the moistened permeable material is presented to the incoming air, and conse-' quently the said 'air will pass through the moistened permeable material at a slower rate, and therefore be incontact with it for a longer time, and so increase the conditioning effect on the air, while the resistance to the passage of the air is lessened. I

The means for coolin or heating the air before or after it passes tfirough the moistened permeable material and the means for distributing the conditioned air into the room and referred to in the aforesaid s ecification of Letters Patent of the United tates, No.

' 691,312, January 14, 1902; but the permeable material is arranged in the air passage-or chamber or caslng contaimng it. in a number of folds or depending loops or series of sages for the incoming airis constitute .tween the folds, and another set of passages sheets, which hereinafter and in the claims I will refer to as folds, suspended or supported in such a manner -that a set of dpas lace may be of any convenient- /k1nd si1'c for example, as those describedfor the outlet of air is constituted within the folds, the air passing through the very extensive area of moistened permeable material on its way from one set of passages to the other.

The accompanying drawings represent constructions 1n accordance with my invention; but I do not limit myself to the precise construction illustrated. In the several figures corresponding parts are marked with l the same letters of reference.

. Figure 1 is a transverse sectionon the line 1 2, Fig. 3. Fig. 2 is a vertical section on the line 3 4, Fig. 1; and Fig. 3 is a section on the line 5 6, Fi 1, of a construction such as is described an shown in the specification of my aforesaid patent, N o. 691, 312, but with my present invention applied thereto. Fig. 4 is a vertical section on the line 7 8, Fi 5, with the doors of the casing removed. %ig. 5 is a vertical section at right angles to Fig. 4. Fig. 6 is a sectional plan on t e line 9 10, Fig. 5. Fig. 7 is a detail view of a modification. Fig. 8 is a vertical section of a modification. Fig. 9 is atransverse section showing a different arrangement of folds. Fig.- 10 is a transverse section showing the folds arranged crosswise. Fig. 11 is a vertical section of a water-trough and of a modified form of water-trough. Fig. 12 is a plan views showing different modifications of the framework supporting the permeable material run out of its casing. Fig. 15 is a perspective view of the casing; and Fi 16 is a similar View of the-same, showing 1; ebpposite side.

Thepermeable materiafA is arranged vertically in saw-tooth fashion, the uprightsa, connected to the trough above and the trough below, keeping the material properly distended- By extensions of of the crmeable material di ping into the troug B and secured by hoo water supplied by the ipe b (by a tap or taps to whic access may he had throu h a door or doors in the casing or chamber) 1s conducted to the main body of the permeable material A, from the said trough B, which corresponds in form to the arrangement of the permeable material A, surplus, water being received in the bottom trough O and passin off by the pipe 0. External air enters as s ownby the arrows and passes into the passages d between the folds of the permeable material A through the said permeable material, and thence throughthe passages e between the folds of the permeable material and through the pipe F to the lace of utilization.

represents the coil for attemperating the incoming air.

If desired, instead of the main body of the permeable material having extensions to dip into the water-trough B separate pieces of permeable material or wicks can be used to hooked in the end troughs B and being depressed in the other troughs B by either hollow bars h, with a slot or openings at bottom, or by rods, as at i. The troughs B are supplied with water under pressure by taps on the pipe I). The air is indicated by the arrows as entering from the side of the casing G into the passages d and passing thence through the permeablemater ial into the 'pas- \i rangement analogous to that shown in Fig. 8, j but with the passages d and e between the sage e and therefrom to the outlet F. In this case (and in the otherconstruction, where necessary) the air can be prevented from passing between the edges of the permeable materi and the casing or support by guards a? on the side of the permeable material 0 posite to that at which the air enters the sai material. These guards a may be angle-bars, which constitute also the uprights of the support,

being connected at top by cross-pieces to carry the water-troughs B and connected to the surplus-water trough C, the spaces between these uprights being preferably completely covered by a' plate or plates on the side opposite to that at which the air" enters and having plates on the air-entrance side covering only thespaces e at the side, (leaving them open above,) but leaving 0 en the side communications for air to enter 516' passages d. "Thebars or rods h 'i can be removably secured by s uare or other shaped projections at their ends passed into slots in the ends oi the water-troughs and secured by catches.

In this construction I have shown wheels 1,

upon which the structure supporting the moistening and filtering construction is carried, so that it can be run out from and-back into the casing G, which is provided with tightly-closable doors for the purpose. The supports for the permeable material are secured to the trough O and so are run in and out with it. The air can enter from below, if desired, and in that case the trough C for the surplus Water will be replaced by separate troughs 0 as shown in Fig. 7, to allow of ter-troughs seaese openings between them for the entrance of air, as shown by the arrows.

Fig. 8 is a vertical section of another arrangement with the loops of permeable material A arran ed horizontally. there being waat each end, into which part of the permeable material passing over the guides formed by the curved edges of the troughs B is kept depressed by rods 'i, the ends of the said material being secured in the uppermost and lowermost troughs by hooks.-

The air entering the casing G, as indicated by arrows, may in this as well as in the other arrangements first come into contact with an attemperating-coil K, and the said air passes in the direction of the arrows to the exit F from. .the casing to the place where it is to be used.

Fig. 9 is a transverse section showing the lower ends of the loops of permeable mate ial A arranged at different levels, so that the air entering in the direction indicated by the arrows has ready access to the passages d between the loops of permeable material A. In this arrangement the permeable material is Fig. 10 is a transverse section of an arpermeable material A arranged crosswise of the casing G instead of lengthwise thereof, the air entering the passages d, passing through the permeable material A, into apassage leading to the outlet F. The said material is held in the troughs, as in Figs. 8 and 9.

Fig. 11 is a vertical section, and Fig. 12 is a plan showing a modification in which the permeable material A is passed over rods or bars, as at 17, and there is a water-trough B above, which has slits b in its lower part and guides 6 for directing the'water. The said trough B is preferably divided by partitions, as at b, to equalize the supply of water, and is p rovided with squared end pro'ections to be held in slots in the casing or in t e structure capa- ,ble' of being slid into and out from the casing or chamber.

. The rods or supports for the permeable material and also the 'water-tro hs may in all the constructions be connecte to the casing or the-structure in the casing or chamber in any convenient way, and such of them as have to be removable may be secured by screws 01' catches or other means of securing vided for outgoing air, and means for su pl ying water to the loops of the folds of sai permeable material.

2. An apparatus for ventilatin having an air-passage containing a sheet 0 permeable material arranged in a plurality of folds, so that a set of passages is provided for the incoming air and another set of passages is provided for outgoing air, in combination with meansfor supporting the permeable material in folds and meansto deliver water to the loops of the folds of the permeable material.

3. An iapparatus for ventilatin having an air-passage containing a sheet 0 permeable material arranged in a plurality of folds so that a'set "of passages is provided for incomingl air and another set of passages is provi ed for out oing air in combination with supports for t e folds of said permeable material, and troughs for supplying water thereto, into which troughs the ends and loops of the sheet oi permeable material dip.

4. An apparatus for ventilating, having an air-passage containing a sheet of permeable material arranged in a plurality of folds, so that a set of passages isprovided for incom in air and another set of passages is provi c led for outgoing air, and means whereby the folded sheet of permeable material can be run into and out of place.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
